ADJUSTABLE GUSSET FOR ENVELOPS.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed July 27, 1918. Serial No. 246,971.

To all whom it may concern:

Be it known that I, RUDOLPH BELOHER, a citizen of the United States ofAmerica, and a resident of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements inAdjustable Gussets for Envelops, of which the following is aspecification.

My invention relates to an adjustable gusset or partition for envelopsand has for its object the construction of a partition which may bereadily applied to large envelops and which may be manually shifted fromplace to place so as to divide the envelop into compartments of anydesired proportions.

In the drawings- Figure 1 is a perspective view of an envelop showingthe partition in place;

'Fig. 2 is a section on line 22 of Fig. 1;

Fig. 3 is an enlarged section on line 33 of Fig. 2; and

Fig. 4 is a perspective view of the partition detached.

The envelop E is of the heavy paper type and has the ordinary bellowsedges B at its bottoms and ends. It is open above and ordinarily has therear edge C higher than the front edge D. That difference in height,however, is for other purposes and has nothing to do with the presentinvention.

The partition P is preferably of the same material as the envelop and isfolded as shown in the drawings so that it will have the same bellowsaction as the edges B.

On one. edge of the partition 1? is a short metal clip F and on theother edge is a long metal clip H. The upper ends of these clipsterminate in hooks F for en aging the edge D and H for engaging t e edgeC. These hooks are so made that when the partition is in place they willpinch the edges C and D and hold the partition in place by friction onsaid edges.

The clips F and H have their lower portions bent around the edges of thepartition P as shown in Fig. 3, and those clips are held to the edges ofthe partition by friction. They may, of course, be secured in otherways, but friction is sufficient for the purpose. The connection betweenthe clips and the edges of the partition P is secured by putting themunder a press which will make the frictional contact sufiicient towithstand any strain less than that enough to tear the paper. Thefrictional contact between the hooks and the edges of the envelop is,however, much less and only enough to normally prevent the partitionfrom slipping.

The drawings show only one partition in the envelop E. It will beevident, however, that any number of similar partitions may be used inthe same envelop, and that the partitions may be manually adjusted toany position.

What I claim is:

1. A partition for envelops consisting of a body P folded as shown, andclips secured to the edges of said body, said clips being provided withhooks adapted to engage and have frictionalcontact with the edges of theenvelop with which the partition is to be used.

2. An adjustable partition for envelops consisting of an expandablebody, and clips clamped upon the outer edges of said body, said clipshaving hooks adapted to engage the upper edges of the front and back ofan envelop, and said hooks being arranged to have a light frictionalcontact with said e ges.
